Extralite ExtraBolt 18 ultralight Center Lock disc brake rotor locking ring. Made of 7075T6 CNC aluminium, thanks to the super refined design weighs only 5.45 grams and it's one of the lightest on the market and allows a weight saving of over 30% compared to the original Shimano one. Compatible with all Center Lock hubs and disc brake rotors. Comes in black or silver anodized finishing with the laser engraved "Extralite" logo. Can be tightened with a Shimano TL-UN70 type wrench or with a compass tightening wrench with 3 mm diameter pins (maximum tightening torque 30 Nm, thread length 5.3 mm). The package include a single ring nut, so for a complete bicycle you will need to purchase two. 100% Made in Italy.
